Java program converts stack trace to string

Java Examples Comprehensive

In this program, you will learn how to convert stack trace to string in Java.

Example: Convert stack trace to string

import java.io.PrintWriter;
import java.io.StringWriter;
public class PrintStackTrace {
　　　　public static void main(String[] args) {
　　　　　　　　try {
　　　　　　　　　　　　int division = 0　/　0;
　　　　　　　　} catch (ArithmeticException e) {
　　　　　　　　　　　　StringWriter sw = new StringWriter();
　　　　　　　　　　　　e.printStackTrace(new　PrintWriter(sw));
　　　　　　　　　　　　String　exceptionAsString　=　sw.toString();
　　　　　　　　　　　　System.out.println(exceptionAsString);
　　　　　　　　}
　　　　}
}

When you run the program, the output will be similar to the following content:

java.lang.ArithmeticException:　/　by　zero
　　　　at　PrintStackTrace.main(PrintStackTrace.java:9)

In the above program, we force the program to throw an ArithmeticException by dividing 0 by 0

In the catch block, we use StringWriter and PrintWriter to print any given output as a string. Then we use the exception's printStackTrace() method to print the stack trace and write it to the writer

Then, we just need to use the toString() method to convert it to a string.
